To turn off color management on a CUPS print job you have to turn on calibration mode. On the command line it is done as follows:
lp -d printer -o cm-calibration=1 file The option has the possible values 0 and 1. The button mentioned should probably add this option to the print job, or when it is not in the context of printing a job but managing a print queue it should set the default of this option on the print queue. The option is available for all printers (provided by cups-filters). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1855615 Title: Device colour profiles - on / off button not working Ubuntu 18.04.3LTS To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-control-center/+bug/1855615/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
